BitIOTest1
这是一个练习使用位写入/写出的程序,利用bitio.c和bitio.h工具整合,可以向文本文件E:\bitio1.txt中读取和写入数个位,使用者可以通过调试功能进一步了解位写入写出的作用。进而给今后做数据压缩打下基础。(This is a practice using bit write/write program, using bitio.c and bitio.h tool integration, you can read and write several bits to the text file E: \ bitio1.txt, the user can pass Debugging function to further understand the role of bit write write. And then lay the foundation for future data compression.)
